我正在尝试在Apache tomcat和My sql上运行Web应用程序。之前它是在oracle 11g和wildfly上运行的,它运行正常,请找到下面附带的xml配置文件。提前谢谢。
这是我的调度程序-servlet.xml

答案
如果您使用的是mysql 改变你的hibernate属性
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="packagesToScan" value="com.spring.ars"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="show_sql">true</prop>
</props>
</property>
</bean>

错误似乎表明您的类路径中没有MySQL驱动程序:
无法加载JDBC驱动程序类[com.mysql.jdbc.Driver]
请确保在你的应用程序WEB-INF / lib文件夹或tomcat lib文件夹中有正确的MySQL连接器/驱动程序:https://dev.mysql.com/downloads/connector/j/5.0.html
如果您没有手动添加它,或者如果您在项目中使用maven,则可以将其添加到您的pom.xml中:
<!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>6.0.6</version>
</dependency>
